Security Bulletin


Summary

Vulnerabilities were identified within Docker shipped as pattern type (pType) component with Cloud Pak System Software. IBM Cloud Pak System Software addressed these vulnerabilities [CVE-2023-28840, CVE-2023-28841, CVE-2023-28842].

Vulnerability Details

CVEID:   CVE-2023-28840
DESCRIPTION:   Moby is vulnerable to a denial of service, caused by an unprotected alternate channel within encrypted overlay networks. By sending a specially crafted request to inject arbitrary Ethernet frames into the encrypted overlay network, a remote attacker could exploit this vulnerability to cause a denial of service condition.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/251927 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:C/C:N/I:H/A:L)

CVEID:   CVE-2023-28841
DESCRIPTION:   Moby could allow a remote attacker to obtain sensitive information, caused by the missing of encrypted sensitive data within the overlay network driver. By sending a specially crafted request, an attacker could exploit this vulnerability to obtain sensitive information, and use this information to launch further attacks against the affected system.
CVSS Base score: 6.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/251928 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:N/A:N)

CVEID:   CVE-2023-28842
DESCRIPTION:   Moby could allow a remote attacker to bypass security restrictions, caused by an unprotected alternate channel within encrypted overlay networks. By sending a specially crafted request, an attacker could exploit this vulnerability to inject arbitrary Ethernet frames into the encrypted overlay network by encapsulating them in VXLAN datagrams.
CVSS Base score: 6.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/251929 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:C/C:N/I:H/A:N)

Disclaimer

According to the Forum of Incident Response and Security Teams (FIRST), the Common Vulnerability Scoring System (CVSS) is an "industry open standard designed to convey vulnerability severity and help to determine urgency and priority of response." IBM PROVIDES THE CVSS SCORES ""AS IS"" WITHOUT WARRANTY OF ANY KIND, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. CUSTOMERS ARE RESPONSIBLE FOR ASSESSING THE IMPACT OF ANY ACTUAL OR POTENTIAL SECURITY VULNERABILITY. In addition to other efforts to address potential vulnerabilities, IBM periodically updates the record of components contained in our product offerings. As part of that effort, if IBM identifies previously unidentified packages in a product/service inventory, we address relevant vulnerabilities regardless of CVE date. Inclusion of an older CVEID does not demonstrate that the referenced product has been used by IBM since that date, nor that IBM was aware of a vulnerability as of that date. We are making clients aware of relevant vulnerabilities as we become aware of them. "Affected Products and Versions" referenced in IBM Security Bulletins are intended to be only products and versions that are supported by IBM and have not passed their end-of-support or warranty date. Thus, failure to reference unsupported or extended-support products and versions in this Security Bulletin does not constitute a determination by IBM that they are unaffected by the vulnerability. Reference to one or more unsupported versions in this Security Bulletin shall not create an obligation for IBM to provide fixes for any unsupported or extended-support products or versions.
